[gdal-dev] TIFF with different KEYS_DS

[Jorge Martin]

Hello Frank,


I am reading libtiff manual and it is possible to write different IFD
(directories, I do not know the correct word) in the same tiff file
using *TIFFWriteDirectory
*function. Is it possible to use it in gdal library?


Many thanks,


Jorge
